The article reports on the Etymological Dictionary of the Old Church Slavonic Language, which was completed at the end of 2022. It is the first extensive scientific etymological vocabulary of Old Church Slavonic, consisting of a total of 21 volumes, of which 19 volumes contain entries (there are 2483 entries on 1164 pages). The last two volumes are registers of all words listed in the dictionary.

The use of Church Slavonic texts as resources for the study of the history of Macedonian language requires a serious deep level analysis in order to defi ne the structure of the Church Slavonic language system on all its level. The structure of the literary language can be differentiated in several types of features: specifi c literary features unknown in the dialectal language; hybrid features, i.e. features based on dialectal grounds but developed in Old Slavonic in a specifi c way; dialectal features of various origins, differentiated chronologically or locally. The Macedonian Recension of the Church Slavonic language from its gradual beginning during the 11th century, especially in the second half, reaches its full development in the 12th century, when there is a consolidation of the basic norms of the Macedonian Church Slavonic literacy. The consolidation of these norms is connected and in continuity with the Old Slavonic Glagolitic period in the work of the Ohrid literary center. The paper presents representative examples that characterize the language of the Macedonian Old Church Slavonic literacy on orthographic, phonological, morpho-syntactic and lexical level.

The article offers a survey of works of Ukrainian linguists in the field of Church Slavonic, in particular its Ukrainian recension. While applying the historiographic approach, the author focuses on various publications and the study of the language of some records and their authors, and the reconstruction of orthoepy. The article also discusses some controversial questions of the interrelation between the Ukrainian (southern) and the Great Russian (northern) redaction of the Church Slavonic language from the second half of the 17th century onward. The author also highlights changes in the methodological principles and argues that, despite the use of sociolinguistic and cognitive methods along with the traditional structural and functional approach, the current discourse in Ukrainian linguistics appears to be incomplete.

Since modern Slavic studies lack a uniform concept of the Ukrainian redaction of the Church Slavonic language, this article analyzes the major achievements of Ukrainian linguistics in the study of this phenomenon. Applying the method of linguistic historiography, the author describes the emergence of a national concept, according to which written sources – reflecting the features of the Ukrainian language from different periods of its formation – attest to the existence of a single Ukrainian redaction. The development of views on the Church Slavonic language is evidenced by the works of M. Maksymovych, I. Ohienko, G.Y. Shevelov, V. Nimchuk. Today different schools are primarily concerned with the quantitative interpretation of particular features of the Ukrainian redaction. Such an interpretation is largely premised on the 19th‑century Russian philological tradition which does not take into consideration the historical differentiation of East Slavic. Burdened with problematic terms like Russian, such an approach remains in contrast with Ukrainian linguistics, which accepts the existence of the Ukrainian redaction of Church Slavonic since the times of Kyivan Rus’.
